Hello dear Student,
My name is Alexandr, I'm 20 y.o. and I am a professional parkour athlete. I've been practicing parkour since 2006. Back then we had to learn every move by ourself without any side information, so now I know I'm familliar with a lot of different techniques and styles. As well as viewing the lessons, you are welcome to visit my YouTube account to see the showreels and other professional videos!
